DeployableFiles should be setup for ExistingLocalConfiguration

Description

When using the daemon to deploy a war to an existing weblogic server, the war was not appearing in the autodeploy folder.

Attached patch for this.

This is a logic improvement since as per the LocalConfiguration interface's Javadoc, the configure method for all local configurations (existing or standalone, doesn't matter) should: (quote) "setup the container which means setting up a valid directory structure, setting up configuration files and deploying static deployables".
